SPECIFICATION forming part of Letters Patent No. 637,781, dated November28, 1899.

Application filed February 20, 1899. Serial No. 706,089- (No model.)

To all whom it may concern.-

Be it known that I, HARRY K. HEADLEY, a citizen of the United States,residing at East Liverpool, in the county of Oolumbiana and State ofOhio, have invented or discovereda new and useful Improvement in PottersTools, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification, in which- Figure 1 is a View in side e1evation,.showingthe application of my improvement to a molding apparatus forearthenware. Fig. 2 is an enlarged detail View in side elevation of thetool-clamping device forming the subjectmatter of my present invention.Fig. 3 is a cross-sectional view taken in the line III III of Fig. 2.Fig. 4 is a plan view thereof, partly in section, as indicated by theline IV IV of Fig. 2. Fig. 5 is a similar view indicated by the line V Vof Fig. 2. Fig. 6 is a similar View on line VI VI of same figure. Fig.7is a detail perspective View of the clampingyoke. Fig. 8 is a similarview of the adjusting or backing strip.

My invention relates to tool clamps for moldingmachines for shapingarticles in earthenware; and it consists of a head adapted to be mountedin the machine and to receive and hold the shaping-tool in such a mannoras to render it very efficient and exact in operation, easily andquickly removed, and to provide for rapid and accurate adjustment.

Referring now to the drawings, 2 represents the usual housing, withinwhich is partially mounted the socket-arm 3, adapted to receive theshank 4 of the tool-clamp. At the outer end of such shank is the head5,thr0ugh which extends a longitudinal slot 6 between upper and lowerhorizontal body portions 7 8 of the head, joining which portions at theback is the connecting-bridge 9, forming a bearing for the clampingscrew-bolt 10. The yoke 11 is provided with a vertical slotted opening12, adapted to receive the tool 13, such opening being somewhat Widerthan the thickness of the tool, and between the integral back and frontportions 14 15 and ends 16. At the middle portion the back isreinforced, as at 17, in which reinforcement is secured, preferably bycasting therein, the clamping bolt 10, threaded at its outer end, suchreinforcement being adapted to enter and have a lateral movement withina corresponding enlargement 18 in the head. While such reinforce mentprovides strengthening means for the portion of the yoke to which thebolt is secured, it will be understood that such construction is notabsolutely necessary and may be dispensed with.

The front face 19 of the portion 8 of the head is somewhat recessedbeyond the face of the upper portion 7 sufficient to admit of theinsertion of the adjusting-plate 20, which is mounted on sliding pins21, entering corresponding sockets in the lower member 8 and preferablyriveted at the ends to prevent withdrawal, such pins being capable ofsuffi cient movement longitudinally in the sockets to permit of theadjustment of plate 20. This plate is set outwardly by set-screws 22 toadjust it even with the face of member 7, or beyond the face of member 7in case it is desired to set the tool at an angle.

The tool A is of the usual or any desired construction adapted to thisclass of work, beinguprovided with a forming-templet or shaping edge aat its lower extremity, made to conform to the desired shape of one-halfof the diametrical contour of the article to be made, as will be wellunderstood by those skilled in the art to which this invention re=lates.

The tool A is set within the head and maintained as to its verticalposition by two slotted links 23 23, to which the tool is clamped by asecuring-bolt 24, passing through the tool and slots of the links, bywhich it is rig= idly set with relation to such links and its elevationin the head regulated, as is usual with this class of tools. The head isprovided with an abutment 25, against which one of the links bears tolimit its movement and insure proper location when reinserting in thehead after removal, the tool having been set properly with relation tothe links. The head 5 is provided with an extended handle 26 of anydesired length by which the head is raised and lowered upon the pivotedsupport 27in the housing. Downward motion is limited by an adjustablebearing 28, adapted to contact with an extension 29 of the housing.

The tool having been inserted within the clamp, the tightening-bolt 10is screwed up be inserted very quickly and accurately departing, from myinvention,- sincetI 'd'on-ot:
